or what cars have the same part used in my car i have seen such a site but dont remember how to cross reference vehices
Thanks
I am hoping someone may have some insight on the issue I am having with my 2005 Dakota.
No dash lights are signaling an error, but when I stop on a slick surface my ABS system turns on for a second or so then the truck starts sliding until it stops. Very rarely does the ABS system turn on after the first attempt, and if it does it is only for another second. We just had a heavy snow storm so it is easy to test out. Again I can feel the truck sliding and the ABS kicks on for a second and then stops working.
When I turn the truck on the ABS light turns on as normal for a few seconds then turns off. There is no other identification of an issue that I know of besides the fact that the ABS does not work properly.
Thank you for taking a look and for any help

This morning I started the engine and, as I also notice now and then, the starter wouldn't engage on the first try, but did on the second. This may be something to do with the new ignition switch (after market item) and the replacement operating rod that goes from the key cylinder to the ignition switch (Dodge item $100!) that I put in last year.
Could the starter failing to start on the first try trigger the 41 code? I'm just guessing here, but it seems the Check Engine light coming on and the starter not engaging on the first try both began to happen around the same era.
properly to control the battery charge. Therefore, the battery is not up
to full charge and the solenoid will click trying to engage the starter because
the starter draws hundred amps or so from a partially discharged battery,
so the voltage (normally 12.6 volts) drops down to 10 volts or less.
On the Dakotas the PCM (ECM) controls the field current for charging purposes. If the field is shorted, or the field brushes worn down, the
PCM which acts as a voltage regulator for charging the battery, can't
provide the required charge because of the problem with the Alternator.
According to my 1998 Dakota Haynes manual (and you should get one
for yours if you can read electrical diagrams), the generator output (current) is
via a 140 amp fusible link located in the PDC (power distribution center)
on the left fender next to the battery. The rectified o/p of the alternator
goes directly to the battery through this fusible link.
The voltage(and a small amount of current, required to excite the field
of the generator is controlled by the ECM/PCM through a separate winding
on the alternator called the exciter winding. There are two connections to
this winding direct from the ECM..one is "generator field driver connection"
on ECM/PCM connector C2, the other connection is the "generator field source" on connector C3., which has a "regulated and controlled field current. If the exciter field winding is shorted or not functioning because
of bad brushes on the two field winding connection slip rings, then the
field cannot "switch on or off" to regulate the state of charge to the battery.
So to summarize:
1. It's a discharged battery directly resulting from a problem with your
alternator, and the ECM/PCM is trying to tell your that via code 41.
At this point I'm gonna have to have it towed I think.
store that sells some automotive products.
The OBDII code reader will give you the P-codes, which are very easy to
interpret.
The stalling could be due to a low charged battery..especially if it has
a hard time turning over in colder weather, when weak batteries start
showing their age and inabilty to supply cranking amps.
If the battery voltage is below 10volts, most of the sensors could be
affected as well, and that could cause the engine to die, as the TPS
sensor depends on a good regulated 5V being supplied from the PCM.
same with the Cam and crank sensors.
Test the battery voltage no load (ignition off)..if it's not reading 12.6 volts,
then the battery is undercharged. That could be due to charging problem
or most likely the battery itself if it is more than 4 years old.
It's easy to test the battery..put a digital voltmeter across the battery
terminals and crank the engine..if it's "grunting" or the starter solenoid
is clicking..it's the battery not able to supply the starter.
Recently, and I mean all within about 24 hours, my truck experienced very different symptoms. The first was that my cd player will no longer eject cds. While this is possibly not related to the other 3 it is just weird it happened at the same time so it is worth mentioning. The next was my fuel gauge stopped working, then the check engine light came on. I received 3 codes, B2100, P0463, and P0700. After looking up the codes they stand for the following:
B2100 - Low Battery Voltage
P0463 - Fuel Level Sending Unit Volts Too High
P0700 - Check Transmissions DTCs
This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code)
My first thought was this had to be electrical so I replaced all battery hardware and expertly cleaned the terminals. Didn't fix. I then checked all the fuses (couldn't check relays) and found one blown for towing lights ... and it didn't fix it. Now I'm just confused and would really appreciate any help. Going through the forums I've seen a ton of posts about the P0700 code but I'm not having any noticeable tranny problems like most the posters complain they experience. The tranny is less than 30k miles old and is shifting great. I'm feeling or hearing no weird noises or anything.
As far as the truck it is an 05' Dakota 6 cylinder standard model with only the towing package upgrade. It has just over 140,000 miles, still runs good, and gets it's EPA estimated fuel economy. I just recently dropped the tranny pan and replaced the filter, all the fluid, and the surrounding gasket. The oil is changed approx. every 3k but as I drive a lot of highway miles if I go to like 3.2k or so I'm not overly concerned. I use all synthetic oil with usually mobile-1 filters unless a nicer brand has a really good sale on. It does have a cold air intake long with - and I'm not sure of the name as it was preinstalled when I bought it - an oil airater. For the cd player it is the standard 1 disk and is stock. The previous owner was a car mechanic so here is hoping he took care of it like he said he did.
55 is "end of codes" but the others should all be 2 digit numbers... so you have either x3 and 32, or 33 and x2, or 33 and 2x ahead of the 55. Need to find out what that "x" is.
